[0025] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid obscuring the essence of the present invention, well-known methods, processes, procedures, and components are not described in detail.

[0026] Furthermore, persons of ordinary skill in the art will appreciate that the figures provided herein are for illustration purposes only and are not necessarily drawn to scale.

[0027] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include," "comprising," and similar words should be construed in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to."

[0028] In the description of the present invention, it should be understood that the terms "first," "second," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0029] Reference Figure 1-2 The utility model provides a simple diversion device for river channel construction during the dry season, which is used for river channel diversion. A simple diversion device for river channel construction during the dry season includes a support rod 1, a composite waterproof board 2 and a sand and gravel footing material 3. A plurality of support rods 1 and a plurality of composite waterproof boards 2 are provided. The composite waterproof board 2 is provided between two adjacent composite waterproof boards 2, and the height of the support rod 1 is higher than the height of the composite waterproof board 2. The plurality of support rods 1 and the composite waterproof boards 2 are connected together in sequence and fixed above the river channel. After the support rod 1 is fixed to the riverbed, the sand and gravel footing material 3 can be taken on site to fix the diversion device, and the river channel can be cofferdamed and diverted.

[0030] The lower end of the support rod 1 can be fixed on the riverbed, and the gravel footing 3 is laid below the support rod 1 and the composite waterproof board 2. The laying height of the gravel footing 3 is higher than the lower side of the composite waterproof board 2. The two sides of the composite waterproof board 2 are connected to the support rod 1 so that they can rotate relative to each other. When in use, the diversion device can be placed at the location where the river needs to be diverted, the support rod 1 can be inserted and fixed in the riverbed, and materials can be collected on site. The gravel footing 3 is laid at the same height as the lower side of the composite waterproof board 2, and the diversion device is stably fixed in the river. The composite waterproof board 2 and the support rod 1 can rotate relative to each other, and adjacent composite waterproof boards 2 can be folded for easy transportation.

[0031] The support rod 1 includes a main steel drill 12, a connecting plate 11 and an auxiliary steel drill 13. The lower ends of the main steel drill 12 and the auxiliary steel drill 13 are both pointed and can be inserted downward into the river channel. The main steel drill 12 is fixed to the lower side of the connecting plate 11, and the main steel drill 12 is vertically arranged. There are two auxiliary steel drills 13, and the two auxiliary steel drills 13 are arranged on both sides of the main steel drill 12. The upper end of the auxiliary steel drill 13 is hinged to the connecting plate 11, which can swing the lower end of the auxiliary steel drill 13, thereby adjusting the relative angle between the auxiliary steel drill 13 and the main steel drill 12, so that the auxiliary steel drill 13 and the main steel drill 12 are tilted. The position of the lower end of the auxiliary steel drill 13 is adjusted to make the support rod 1 more suitable. It should be noted that the rotational connection between the auxiliary steel drill 13 and the connecting rod is a hinge shaft (not shown in the figure). This is a prior art and the structure will not be repeated in this application.

[0032] The composite waterproofing sheet 2 comprises a steel mesh (not shown) and a waterproof fabric 21. The waterproof fabric 21 is fitted over and secured to the outside of the steel mesh. The ends of the steel mesh are hingedly connected to the main steel bar 12, enabling relative rotation between the composite waterproofing sheet 2 and the support rod 1. The steel mesh provides stable strength for the diversion device. A sleeve can be secured to the end of the steel mesh, which is rotatably connected to the main steel bar 12. This structure is prior art and will not be further described in this application.

[0033] As an embodiment, the main steel drill 12 and the auxiliary steel drill 13 are located in the same plane. When the auxiliary steel drill 13 rotates and diverges, the connection area between the support rod 1 and the riverbed can be increased. When the auxiliary steel drill 13 rotates and retracts, the volume occupied by the support rod 1 can be reduced, making it easier to carry.

[0034] As an embodiment, the thickness of the steel plate mesh is 1.5-2.5mm. Furthermore, the thickness of the steel plate mesh is 2mm. If the steel plate mesh is too thick, the weight and volume will be too large, and it will not be easy to fold during construction. If it is too thin, the strength will not meet the requirements. The steel plate mesh in the above range can provide better strength and can meet the strength requirements of the guide device.

[0035] The implementation principle of the present invention is: when in use, the diversion device can be placed at the position where river diversion is required, the support rod 1 can be inserted into the riverbed and fixed, materials can be obtained on site, and sand and gravel pressure materials 3 can be laid at the height of the lower side of the composite waterproof board 2, and the diversion device can be stably fixed in the river, and the composite waterproof board 2 and the support rod 1 can rotate relative to each other, and the adjacent composite waterproof boards 2 can be folded for easy transportation.

[0036] Those skilled in the art will appreciate that, provided there is no conflict, the above preferred solutions can be freely combined and superimposed.

[0037] It should be understood that the above-mentioned embodiments are merely illustrative and non-restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will be included in the scope of the claims of the present invention.
